I can extract side effects

Ning City, Provincial People's Hospital, Department of Intervention.

A rush of phone calls rang.

"There are emergency patients!"

The members of the department who were resting jumped up one after another as if they heard the alarm bell, and activated the catheterization room with one button, preparing for the preoperative preparation.

"I'm Li Qing, what's the patient's condition?" Li Qing answered the phone and asked carefully.

As the deputy chief doctor, he and Director Yao respectively lead a team, which rotates day and night, and is always ready to operate on patients.

Director Yao is not in the department right now, and he will be fully responsible for emergency surgery.

"The 72-year-old patient was admitted to the hospital due to acute myocardial infarction. His vital signs were extremely unstable. After being rescued by electric defibrillation in the emergency department, he suffered repeated ventricular fibrillation on the operating table and had stopped breathing. His condition was very critical."

"In this case, the emergency department can no longer take over. It needs to be sent to you for aortic interventional surgery, and it may be possible to rescue it."

After hearing about the condition, Li Qing's expression became extremely serious, and he said in a deep voice, "Okay, send the patient's film first, I'm making preoperative preparations here, and the operation will be performed as soon as the patient arrives."

After hanging up the phone, he clapped his hands and gathered the members of the department.

Looking at the patient's examination report on the screen, everyone's expressions became extremely solemn.

Old age, acute myocardial infarction, apnea, and possibly underlying diseases.

In short, the patient's condition is very dangerous.

Li Qing looked at the faces of everyone, smiled slightly, pointed to the patient's scanned image, and said.

"Although the patient is very dangerous, there is still a high possibility of being rescued. Look here, the aorta of the heart is severely blocked, which led to acute myocardial infarction."

"I am going to install the aortic balloon counterpulsation on the patient, open the blood vessel, send the guide wire through the occlusion, and then place the stent, so that the patient can be rescued."

"We have done the same operation before, and we already have a wealth of experience. Everyone sees the tricks, and we will definitely be able to snatch the patient back from death."

After this encouragement, the morale in the department was immediately boosted.

Not long after, the patient was sent to the interventional operating room.

After some communication with the family members, everyone learned key information such as the location of the patient's disease and the degree of stenosis of the blood vessels in a short period of time, and determined the surgical plan.

Li Qing came to the changing room, changed into a blue light isolation suit, and went to the washing room next to him to wash his hands.

After washing his hands, he carefully picked up a dark blue vest-like robe hanging on the hanger next to him, and his hands sank immediately.

The gown is an interventional doctor's shirt, stuffed with thick lead to block radiation during surgery.

Since interventional surgery requires extremely high operational sensitivity of the doctor, an angiography machine must be used during the operation. The X-rays emitted by it will cooperate with the contrast agent to make the blood vessels in the human body look clearer, which is beneficial for doctors to diagnose and perform operations.

During the operation, doctors and nurses must stand in front of the operating table to operate. Although lead clothing can block the radiation, the parts below the knee joint, arms, hands, face and other parts are exposed and exposed to radiation.

There are also lead glasses to protect the eyes, but often during surgery, wearing glasses will affect the operation, and doctors simply don't wear them.

Interventional surgery generally takes nearly an hour, and complex diseases take longer. In this way, the X-rays released by the angiographic contrast agent will affect the medical staff and cause radiation damage to them.

Although lead clothing can block two-thirds of the dose, one-third of the dose will still be absorbed by doctors and nurses, which will cause great damage to the body over a long period of time.

Exposure to X-rays for 10 hours is equivalent to being continuously taken 4000 X-ray films.

Healthy people should control the number of X-rays taken less than 5 times a year, otherwise they may be exposed to a large amount of radiation in a short period of time, resulting in radiation sickness and death in severe cases.

It can be said that the work of an interventional doctor is to injure one thousand enemies and eight hundred self-inflicted injuries.

It is the serious illness that is being attacked, the patient is being saved, and it is oneself that is being injured.

Because the lead coat is too heavy, weighing more than 30 kilograms, it cannot be lifted with one hand, and it needs two hands to lift it.

So he had to raise both hands at the same time, putting them on his body with great difficulty, tightly protecting his entire torso down to the knees.

If it wasn't for Li Qing wearing it every day, he would have already gotten used to it, and his legs and feet would go limp just by picking it up, and his old waist would show off.

The lead clothes are one-piece, and there are also two-piece clothes on the hanger, but he finds it inconvenient to wear, so he always uses this one.

After putting on the lead suit, except for the free movement of the arms, there is no movement in other places, and even moving the body will be a bit difficult.

Li Qing then put on a lead collar, which is used to protect the thyroid gland on his neck.

In addition, there are lead caps, lead glasses, etc., but he is not used to the latter and rarely uses it.

After putting on various protective measures, Li Qing walked into the operating room of the interventional department.

Several doctors and nurses were busy in the operating room. Everyone was wearing heavy lead clothing, and their movements were very clumsy, but they still made all the preoperative preparations.

The operation process is very tense, the incision, the insertion of the pipeline, the identification of the blockage point, and the placement of the stent...

The whole operation was smooth and smooth, very skillful.

After a 2-hour operation, I was sweating profusely all over my body.

Li Qing walked out of the operating room and took off the lead clothing. The surgical gown was soaked and stuck to his back, making him very uncomfortable.

When he put the lead clothes on the hanger, his legs gave way, and he fell to the side. If he hadn't caught the door of the cabinet with quick eyesight, he would have almost fallen to the ground.

He wiped the cold sweat from his forehead, and thought with some fear: "It seems to be too heavy, why don't you wear a split style next time."

After trying again, I struggled to put the lead clothes back on the hanger.

At this time, his whole body was sore and exhausted, and he just wanted to find a chair to sit down and rest.

"After working for more than ten years, I am still getting old after all, and my physical strength is not as strong as before."

Li Qing lamented the passage of time and walked out of the changing room.

Next, it was another busy day. Li Qing performed 7 operations in a row, and the accumulated operation time was close to 12 hours.

By the time he got off work, he was already slumped on the sofa in the lounge, gasping for breath with exhaustion, too lazy to move a finger.

Although these operations were laborious and laborious, what made him feel the most burdened was the lead clothing that cost thirty to forty catties.

After each operation, just take it off a little more briskly, and you will have another operation in a while, so you have to put it on again.

It was simply a 12-hour battle with heavy loads, which exhausted the doctor's mental and physical strength.

Just as Li Qing squinted his eyes and wanted to take a break from the meeting, the door was pushed open heavily.

The red-faced Director Yao appeared at the door. His sharp eyes scanned the audience, and he saw Li Qing huddled in a corner with his eyes closed and rested. He immediately strode over.

"Hey, how tired are you? There are a lot of operations today?" Director Yao couldn't help joking when he saw Ai Jiang's dying appearance.

Li Qing lazily opened his eyes: "Isn't this just waiting for you to come, so I can get off work after handing over."

As soon as the words fell, Director Yao's expression changed and he came over.

"Don't, don't, can't I get up?" Li Qing saw the director's big face close in front of him, and immediately begged for mercy.

Unexpectedly, the director was unmoved, but kept staring at his forehead.

Li Qing casually touched his face, and said blankly, "Director, what's wrong with you, did flowers grow on my face?"

"Don't move, there seems to be a lump on your forehead." Director Yao looked at it for a long time before he asked, "Do you have allergies on your face? How long has it been?"

Li Qing shook his head: "No, when I washed my face in the morning, it was still fine."

After saying this, he suddenly fell into deep thought.

After a while, he slapped his thigh suddenly: "No, it's not an allergy at all, could it be..."

He raised his head to look at Director Yao, and the two eyes met in the air. In an instant, they exchanged countless information and reached a consensus.

Director Yao nodded heavily: "That's right, look at your ray metering pen, I guess it's probably 80% off the chart."

Li Qing suddenly became dejected. He took out a white and orange cylindrical pen from the pocket of his overalls. This is a ray pen provided by the hospital for medical staff who have been relieved of radiation all year round. It is used to detect the annual radiation dose.

Generally speaking, the dose standard established by the International Atomic Energy Agency is that the highest radiation dose in the year should not exceed 50 millisieverts, and the average radiation dose accumulated over five years should not exceed 20. However, this standard is difficult to comply with, and there is no clear definition in China. It is under the control of the hospital itself.

He glanced at the number above, jumped up immediately, and exclaimed.

"What the hell, there's actually 120, which is already far beyond the standard, almost enough for the lethal dose of 200 for severe radiation sickness."

"No wonder I get tired so easily every day. I thought it was because I was getting old. It turned out that it was because of mild radiation sickness. The redness and swelling on my face was also caused by a weakened immune system."

If the radiation dose of the human body exceeds 20, it will cause damage, and if it is less than 100, the immunity will be reduced, and the white blood cells will decrease.

100-200 will lead to mild radiation sickness within a few hours, producing symptoms such as vomiting, diarrhea, fatigue, and a sharp drop in resistance.

200-300 is the lethal dose, which will cause severe radiation sickness, and 30% of the patients will die one after another after 30 days.

By analogy, more than 400 is an emergency, and the 30-day mortality rate is as high as 70%.

As for 1000, it is equivalent to swallowing a piece of heavy metal directly, and the probability of dying within a few days is 100%.

Li Qing's figure of 120 is already quite dangerous, 2.4 times more than the international standard of 50.

Many people are very unfamiliar with radiation sickness, and some mild symptoms are often unexpected.

Fortunately, Li Qing is a professional, and he has always been nervous about this aspect, so he reacted immediately when he had symptoms.

Director Yao said with a serious expression: "You have to get treatment quickly, and then take a radiation leave, guaranteed for at least two weeks, and you can't come back until the white blood cell data is normal."

Li Qing patted his forehead, and said regretfully: "Somehow, this thing is muted, so I didn't hear the alarm."

"You also know that this disease is not curable. There is no particularly effective symptomatic drug at present. I can only try to strengthen my immunity..."

"Wait a minute, who said that there is no suitable medicine." Director Yao suddenly interrupted him, and said, "You interrupted me as soon as I came in, and I almost forgot about the big thing."

"I was just about to tell you that Sanqing Group has developed an antioxidant drug that can enhance the secretion of antioxidant enzymes in the human body, enhance human immunity, and have a strong scavenging effect on free radicals."

"You also know that the principle of ionizing radiation is caused by free radicals running around, so this drug is quite symptomatic for radiation damage."

"Currently, Phase III clinical trials are being carried out in our hospital. As soon as I heard the news, I knew that this drug was absolutely suitable for our interventional department."

Director Yao was talking, his face was filled with joy, and at the same time, there was a faint fear.

"Our department has always been short-staffed, and there are so many operations that everyone is often irradiated, and we haven't had time to take the statutory radiation leave. In fact, I feel ashamed in my heart, for fear of harming everyone."

"You came here halfway. I'm afraid you don't know. Before I became the director, the department was busier and there were no shifts. Everyone was working 24 hours a day. As a result, two tragedies happened."

"One was exposed to radiation for a long time and finally got leukemia. There was also a female doctor whose white blood cells dropped to 1,000 and her chromosomes were deformed, so she had to be transferred from her post."

Having said that, he was silent, and it took a while before he continued.

"Since I became the director, I have increased the manpower and divided it into different teams to perform operations in turn, which has reduced the radiation dose of the entire department."

"Look at you, you are a living example, almost had an accident, it really wasted my painstaking efforts."

Director Yao showed a look of resentment, and then became excited again.

"But now with this new drug, you don't have to worry about your radiation dose."

"Everyone in our interventional department counts as one, from residents to deputy seniors, including nurses and anesthesiologists, all have to test drugs."

With a big wave of his hand, he called all the staff of the department over to tell the good news.

"All of you, those with more than 50 X-ray measuring pens, go to the clinical building early tomorrow morning to apply for the Phase III clinical trial of this new drug."

"You, you, you, I remember that I haven't had a vacation for more than a year. It must have exceeded the standard. I must go this time. I'm watching you all."

Director Yao stretched out his fingers and pointed at them one by one. The faces of the people he touched all showed touched expressions.

Soon, everyone checked their ray measuring pens and found that more than half of the people in the entire department were over 50.

In addition to Li Qing, there are two other nurses who also exceeded 100.

"This..." Director Yao suddenly felt a little embarrassed: "Everyone is going to participate in the clinical trial, who will do the work, what if a patient comes to the door for surgery."

Immediately, someone said: "Director, I can hold on for a while, let's try the medicine after I exceed 100."

"It's okay, I'll take care of it," Director Yao thought over and over again, and finally made up his mind.

"You all go to the surgery, and only a few people are left. I will do the surgery during this time. I just took a vacation a few months ago, and I should be able to last for a while. When you are all cured and come back, I will go again. Test medicine."

"If the patients really can't see it, let them be transferred to a higher-level hospital. Anyway, I'm risking my life, so I can't control that much."

He touched his sparse forehead, there were not a few stray hairs left on it, and he couldn't help laughing at himself.

"When I woke up in the morning, I lost a few more hairs. I applied Sanqing's hair tonic, but it didn't work. Well, it seems that God destined me to sacrifice this hair."

"I think I was handsome and unrestrained back then. I didn't expect that I chose the Intervention Department by a mistake. Since then, I have no chance to have beautiful hair."

When Director Yao, who was in his fifties and with a round figure, began to perform ten years ago, he remembered his youth with a look of regret.

Everyone couldn't bear to look directly at them, and turned around one after another. Those who were off work, those who were working, no one was willing to stay to cheer.

Even Li Qing, dragging his tired body, ran faster than anyone else.

After shaking his head and sighing, Director Yao took a closer look and found that the entire department was empty and no one was there.

He could only shake his head and cursed "these little bastards" in his stomach.

The next day, when more than 20 people from the interventional department came to the clinical building in a mighty way, to sign up for the clinical trial.

The doctor in charge of registration was stunned.

"I'll go, so many people, all of them have radiation sickness?"

"What's wrong? It's not a medical malpractice."

"Your Intervention Department has been taken over?"
